Description

A PWM (Pulse-Width Modulation) switching regulator is an electronic circuit that uses PWM techniques to efficiently regulate and control the output voltage or current of a power supply. PWM switching regulators are commonly used in various electronic devices and systems to convert an input voltage, often from a higher level to a lower level, while maintaining a stable and well-regulated output.

The STR-W6200D series are current-mode PWM ICs that incorporate controller chips. These devices are manufactured using a proprietary high-voltage BCD process, and avalanche guaranteed MOSFETs. These elements allow power supply systems designs that are highly reliable and simple, with fewer peripheral components.

Features and Benefits :

1. Overcurrent protection (OCP) with ac input voltage compensation function; no additional peripheral circuits required—minimizes dependency of OCP on ac input

2. Overload protection (OLP) with integrated timer reduces power stress (temperature rise) at overload condition, requires no peripheral components

3. Avalanche-guaranteed MOSFET improves device capability of withstanding excess surge voltage, providing a simple surge absorber circuit without breakdown voltage derating

4. Start-up circuit eliminates the need for a start-up resistor, and helps to reduce input power consumption Continued on the next page

Description

STR-G6153 is Flyback Converter Switching Regulator for Laser Printer.

An offline quasi-resonant flyback switching regulator is a type of power supply circuit used in offline applications, where the power source is directly connected to the mains voltage (AC line). The term “quasi-resonant” refers to the operating mode of the flyback converter, which combines characteristics of both continuous and discontinuous conduction modes to improve efficiency and reduce switching losses.

The flyback switching regulator is a popular topology for offline power supplies due to its simplicity, cost-effectiveness, and ability to provide galvanic isolation between the input and output. It is commonly used in various low to medium power applications, such as power adapters, LED drivers, and some battery chargers.
